Abstract: A positive electrode material contains at least one positive electrode active material, a solid electrolyte, and a coating material. The solid electrolyte is represented by formula (1), Li?M?X???(1) where ?, ?, and ? are each independently a value greater than 0, M includes at least one element selected from the group consisting of non-Li metals and metalloids, and X includes at least one selected from the group consisting of F, Cl, Br, and I. The coating material covers the surface of the positive electrode active material and contains lithium carbonate.

Abstract: The present disclosure provides vent nibs for use with (e.g., incorporation into) a woodwind instrument, such as a bassoon.

Abstract: The present disclosure relates to a keypad structure for woodwind instrument tone holes, and more particularly, to a keypad structure for woodwind tones which improves the adhesion of a keypad connected to a tone hole tube in which the tone hole is formed in the woodwind instrument, prevents the sound from being exposed to the outside through the tone hole tube and the pad, and can generate excellent resonance so that the resonance of a desired sound can be constantly generated through the closed keypad.
